Surface Plasmon Radiation Forces [PDF]

open access: yesPhysical Review Letters, 2006
We report the first experimental observation of momentum transfer from a surface plasmon to a single dielectric sphere. Using a photonic force microscope, we measure the plasmon radiation forces on different polystyrene beads as a function of their distance from the metal surface.

Sol-Gel Thin Films for Plasmonic Gas Sensors

open access: yesSensors, 2015
Plasmonic gas sensors are optical sensors that use localized surface plasmons or extended surface plasmons as transducing platform. Surface plasmons are very sensitive to dielectric variations of the environment or to electron exchange, and these effects

Designing Plasmonic Gratings with Transformation Optics

open access: yesPhysical Review X, 2015
Plasmonic gratings that support both localized and propagating plasmons have wide applications in solar cells and optical biosensing. In this paper, we report on a most unusual grating designed to capture light efficiently into surface plasmons and ...

Quantum Dot-Induced Blue Shift of Surface Plasmon Spectroscopy

open access: yesNanomaterials, 2022
We experimentally demonstrate the spectral blue shift of surface plasmon resonance through the resonant coupling between quantum dots (QDs) and surface plasmons, surprisingly in contrast to the conventionally observed red shift of plasmon spectroscopy ...

Bouncing surface plasmons

open access: yesOptics Express, 2007
Employing an interferometric cavity ring-down technique we study the launching, propagation and reflection of surface plasmons on a smooth gold-air interface that is intersected by two parallel, sub-wavelength wide slits. Inside the low-finesse optical cavity defined by these slits the surface plasmon is observed to make multiple bounces.

Electrical Excitation of Surface Plasmons [PDF]

open access: yesFrontiers in Optics 2012/Laser Science XXVIII, 2011
We exploit a plasmon mediated two-step momentum downconversion scheme to convert low-energy tunneling electrons into propagating photons. Surface plasmon polaritons (SPPs) propagating along an extended gold nanowire are excited on one end by low-energy electron tunneling and are then converted to free-propagating photons at the other end.

Hyperspectral imaging of gold dimers

open access: yes, 2007
We report on the first realization of a hyperspectral imaging (HSI) technique of surface plasmon polaritons excited in metallic nanostructures by a scanning electron beam.

Gate-tunable plasmons in mixed-dimensional van der Waals heterostructures

open access: yesNature Communications, 2021
Surface plasmons have unique physical properties that make them also interesting for technology. Here, the authors observe plasmons in mixed-dimensional heterostructures that can be highly modulated with electrostatic gating, which may be explained by ...
